TICC2510Fx / CC2511Fx Low-Power SoC (System-on-Chip) with MCU, Memory,2.4 GHz RF Transceiver, and USB Controller 产品概述： The CC2510Fx/CC2511Fx is a true low-cost 2.4GHz system-on-chip (SoC) designed for lowpower wireless applications. The CC2510Fx/CC2511Fx combines the excellent performance of the state-of-the-art RF transceiver CC2500 with an industry-standard enhanced 8051 MCU, up to 32 kB of in-system programmable flash memory and 4 kB of RAM, and many other powerful features. The small 6x6 mm package makes it very suited for applications with size limitations. The CC2510Fx/CC2511Fx is highly suited for systems where very low power consumption is required. This is ensured by several advanced low-power operating modes. The CC2511Fx adds a full-speed USB controller to the feature set of the CC2510Fx. Interfacing to a PC using the USB interface is quick and easy, and the high data rate (12 Mbps) of the USB interface avoids the bottlenecks of RS-232 or low-speed USB interfaces. 主要特性： Radio High-performance RF transceiver based on the market-leading CC2500 Excellent receiver selectivity and blocking performance High sensitivity (-103 dBm at 2.4 kBaud) Programmable data rate up to 500 kBaud Programmable output power up to 1 dBm for all supported frequencies Frequency range: 2400 – 2483.5 MHz Digital RSSI / LQI support Current Consumption Low current consumption (RX: 17.1 mA @ 2.4 kBaud, TX: 18.5 mA @ -6 dBm output power) 0.3 μA in PM3 (the operating mode with the lowest power consumption) MCU, Memory, and Peripherals High performance and low power 8051 microcontroller core. 8/16/32 kB in-system programmable flash, and 1/2/4 kB RAM Full-Speed USB Controller with 1 kB USB FIFO (CC2511Fx ) I2S interface 7-12 bit ADC with up to eight inputs 128-bit AES security coprocessor Powerful DMA functionality Two USARTs 16-bit timer with DSM mode Three 8-bit timers Hardware debug support 21 (CC2510Fx ) or 19 (CC2511Fx ) GPIO pins General Wide supply voltage range (2.0V – 3.6V) Green package: RoHS compliant and no antimony or bromine, 6x6mm QLP36 应用： 2400-2483.5 MHz ISM/SRD band systems Consumer electronics Wireless keyboard and mouse Wireless voice-quality audio RF enabled remote controls Wireless sports and leisure equipment Low power telemetry CC2511Fx: USB dongles  图1。器件方框图。  图2。CC2510Fx 应用电路图(不包括电源去耦电容)  图3。带基本晶体的CC2510Fx 应用电路图(不包括电源去耦电容)  图4。带3次谐波晶体的C2510Fx 应用电路图(不包括电源去耦电容)  表1。外接元件表（不包括电源去耦电容)  表2。CC2510Fx/CC2511Fx应用电路材料清单（BOM） 详情请见数据表： http://focus.ti.com/lit/ds/symlink/cc2510f16.pdf CC1110DK /CC2510DK 开发套件 SmartRF®04DK Development Kit. The SmartRF04DK Development Kit includes a number of functions and applications that allows quick testing of the RF interface and peripherals of the chip. Evaluate the SmartRF®04 products. Right out of the box, the kit can be used for range testing. Use SmartRF® Studio to perform RF measurements. The radio can be easily configured to measure sensitivity, output power and other RF parameters. Prototype development. The SmartRF04DK includes a USB interface that can be used as emulator interface for the CC1110/CC2510. All CC1110/2510 I/O ports are available on pin connectors on the edge of the board to allow external applications easy access to the CC1110/2510. These connectors are also compatible with logic analyser probes for easy debugging.
